In Norway January 10, 1935 4 Claims. (01. 101-91) The present inventionhas for its object improvements in value stamping machines such aspostage stamp cancelling machines, cash registers, ticket printing andamount counting machines or the like, use beingmade of toothed drums orsegments with step-wise arranged teeth co-operating with the respectivewheels in an automatic counting device (hereinafter termed "counter).The invention is distinguished substantially by the fact that the typewheels serving to stamp or print the value (for instance upon a letter,ticket or the like) are rotatably arranged in a member which is in turnmounted rotatably in the machine, the mechanism for adjusting the typewheels being'so arranged that the same, simultaneously with the typeWheel setting, provides for the corresponding setting of the tootheddrums opposite their appertaining wheels co-opcrating with the counter.

% The invention is further distinguished by the fact that the setting ofthe parts for the respective values takes place by means of a mechanismwhich is-driven by the machine and is so constructed that its operationmay be controlled by means of the depressible keys.

By the said arrangements it is possible to produce a value stampingmachine which is particularly simple in construction and is easy andsafe in use, the whole setting consisting only in pressing down the keyor keys corresponding to the desired values.

An embodiment of the invention is iilustrated in the annexed drawings.Figs. la and 11) when taken together show by way of example a postagestamp cancelling machine in front view partly broken away and with thecap or casing in longitudinal section. Fig. 2 shows a machine in planview, the cap being removed. Fig. 3 shows a cross section on the lineIII-III of Fig. 2. Fig. 4 shows in plan view a position of the settingmechanism.

Fig. 5 shows the same in front view partly in section. Fig. 6 is aportion of Fig. 2 and shows a modification for manual setting.

In the drawings the base i of the machine can ries bearings 2 and 3 fora rotatable shaft 4. At

one end of the shaft 4 a printing head 5 is fastened, wherein the typewheels 6 serving to stamp the value are journalled rotatably on a pin I.To each of the type wheels 6 a toothed wheel 8 is attached which mesheswith a rack 9 which is displaceable in the axial direction of the headand by its displacement rotates the gear wheel 8, whereby simultaneouslythe type wheel 6 fastened thereto is turned for setting.

On the shaft 4 four toothed drums iii are displaceably but non-turnablymounted and provided as shown with nine step-wise arranged rows of teethll serving to operate a gear wheel I! which in turn serves to drive theitem wheel oi the counter T appertaining to the respective tootheddrums.

The racks 9 serving to set thetype wheels are extended in the axialdirection of the. shaft 4 and are attached each to one toothed drum IIIin such a relation that, when each drum I0 is displaced for co-operatingwith the wheel II, the corresponding type wheel 8 is set to the valuewhich corresponds to the number of teeth entering in operation on thegear wheel l2.

Each of the toothed drums M has an annular groove I3 receiving a rolleror pin ll of a setting arm l5 swingabie in the horizontal plane andhaving the end which is located behind the shaft 4 fastened turnablyabout a screw Hi, the front end of said arm resting upon a carryingmember II which extends in the longitudinal direction of the machine asshown.

By now swinging the free ends of the arms ll through a greater or lessangle to the right (Fig. 2) from the zero position shown in thedrawings, the respective toothed drums It may be brought into such aposition in relation to their appertaining wheels i2 that any number orthe teeth II will be positioned to operate the said wheel i2 duringrotations of the shaft 4, and simultaneously the respective type wheel 6is so turned that the item corresponding to the number of operatingteeth of the drum Ill is set in printing position in the head 5.

In order to set the arms l5 mechanically in the desired positions andthereby to set type wheels to the desired values, a bar i8 is arrangedin the longitudinal direction of the machine above the free ends of thearms It, said bar it being displaceable in its longitudinal directionand being provided at the right hand end (Fig. 2) with pins or rolls i9,between which the upper end of an arm 20 projects, the lower end ofwhich is mounted turnably on a shaft 2|. At some height above its axisthe arm 20 is provided with a roll 22 projecting into a cam groove 23 ona cam disk 24 fastened to the shaft 4.

0n the underside of the bar II and in front of the arms I! pins 25 arearranged which during the movement of the bar I 8 to the left (Fig. 2)serve to swing the arms into zero position. Further, for each arm iithere is tiltingly attached to the bar II a hook it projecting through aslot l8a in the bar ll behind the arm l5, said hook being pressed downby a spring 21 and serving to move the arm II to the right during thesetting movement of the bar II.

In order to stop the arms II during setting and thereby also to stop thedrums II in the desired settings in relation to the operating wheels llof the counters, vertically movable pins 28 are arranged in the carryingmember IT, a group of ten pins being provided for each of the arms ll.Each group co-operates with one of four rails II, which are retaineddisplaceably in longitudinal horizontal slots in the carrying member I!as shown, said rails being provided with teeth II which may co-operatewith notches II in the pins 28 and are adapted to retain the same in anelevated position, the rails being acted upon by springs 82 which alwaystend to press the teeth II of the rails against the pins 28.

The first one of the pins in each group, the pin 28', is connected by aBowden-wire transmission with a member which '1 acted upon by aneccentric attached to the shaft 4 immediately before the shaft 4, afterhaving completed one revolution, comes into the zero position, so thatthe pin 28' in the resting or zero position of the machine is alwayslifted and held fast by the appertaining tooth on the rail 28, wherebyits upper end locks for the movement of the appertaining arm I to theright.

In its lifted position the pin 28' will act upon an arm 26' attached tothe appertaining hook I, so that the hook it is retained so muchelevated that it cannot act upon and take along with it the appertainingsetting arm iii, when the bar I. is moved to the right. The arm 26' ofthe hook 26 has an inclined face 28" which during the movement of thebar It will act to lift the latter, when the arm 26' strikes against alifted pin II. The other pins in each group are connected by Bowden-wiretransmission each with its depressible key at the front side of themachine, said keys being in usual manner grouped in relation to andprovided with indication of the setting value corresponding to the same.

On the end of the shaft 4 is turnably Journalled a coupling member 36which co-operates with a coupling member 30 carried by a handle or theline 31.

The machine described above operates, when used, in the followingmanner:-

In the position shown in the drawings of the respective parts, which areseen in resting or zero position, all the pins 28' and also all hooks 28are in lifted position. It therefore the machine is started by couplingtogether the coupling members 38, 38, so that the shaft 4 is caused torotate in counter-clockwise direction in Fig. 3, the bar II, by means ofthe roll 22, is at once moved to the right. However, during thismovement the hooks 26, because they are retained in lifted position bythe pins ll are held out of engagement with and pass by the arms I5, sothat the latter are not taken along, and therefore no setting will takeplace. When the shaft 4 approaches its initial position, the bar I8 isagain moved to the left into its initial position shown in the drawings.

when a value stamping is to take place, the key It corresponding theretois depressed, whereby the appertaining pin 2| is lifted into lockingposition, wherein it is retained by the appertaining raiill, whose toothll projects into the notch ll of the raised pin 28. Simultaneously withthe 1mm; of the pin a, the appertaining rail 2: is

displaced to the left against the action of the spring 32. due to itsco-action with the inclined surface of the notch 3| so that the pin 28'of the group to which the lifted pin 2| belongs, is released by the rail29 and falls down, whereby the hook I! is released and projects downhehind the setting arm II.

When the machine is now started and the bar II, as described above, ismoved to the right, the arm I5 and consequently the toothed drum ill ofthe group to which the lifted pin 28 belongs are taken along by the hookit, until the arm 28' of the latter strikes with its inclined face 26"against the lifted pin 28 and thereby is lifted upwarda' Thus the hook26 is disengaged from the arm i5, and the latter comes to rest inengagement with the pin 28, whereas the bar |l continues its movement tothe right, until it reaches is extreme position. When this is reached,the type wheel 6 and the drum II have been moved into the positioncorresponding to the desired value, whereafter the stamping and theoperation of the counter take place.

During the last part of the revolution of the shaft 4 the cam groove 23of the disk 24 causes the bar I! to be moved again back into initialposition. During this movement the hook 25, on account of its inclinedrear surface 26a rides over and behind the arm l5, whereupon the latterand consequently the drum |U are taken along by the pin 25 and carriedback into initial position. Immediately before the shaft 4 has completedits revolution, the said eccentric mechanism will also act upon thefirst-named pin II of the group and will lift the same, whereby the rail29 is moved to the left, so that the set pin 28 falls down again intoin-operative position, whereas the pin 28' again lifts the hook 26 andretains same in in-operatlve position. All the parts now have theinitial or zero position shown in the drawings, and the stamping mayagain take place in the manner described above.

If a series of stampings of the same 'value is to be effected, thefunctions described above must be repeated at each revolution of theshaft 4, but in order to avoid unnecessary movement of the bar i8arepeating mechanism is arranged by means of which the set value may bemaintained during a desired number of stampings.

The arm 20 which serves to move the bar II is rotatably mounted on theshaft 2|, which is in turn displaceable in its longitudinal direction ina carrying member 39 and the casing 40, its inner end being carried by aslide 4| which may be displaced in the longitudinal direction of theshaft 2|. The slide 4| is normally retained in its inner position bymeans of a spring 42. On the shaft 2! an arm 43 is displaceably butnonrotatably arranged, the said arm having a forked end 43a adapted toembrace the arm 20. The said arm 43 is prevented from being displacedtogether with the shaft 2| in its longitudinal direction by means of aU-shaped guiding member 44 (Fig. 2). The carrying member 39 is providedwith a hub 45 having spaced diametrically arranged grooves 46 and 41which have different depths, considered in the axial direction of theshaft 2|, said grooves serving to receive a transverse pin 48 arrangedin the shaft 2|, the groove 48 with the largest depth receiving the pin4|, when the parts are in the normal position shown in the drawings.

If a series of stampings of equal value are to be effected, this valueis set by the depressing of the proper key or keys II. Thereafter theshaft II, by means of a handle 48 attached on its extreme end, is pulledoutwards in its axial direction against the influence of the springs 42and during this movement the pin 48 is moved out from the groove 46 inthe hub 45.

Simultaneously the arm 20 is taken along, and engaged in the forked endof the arm-43, the roller 22 being thus moved out of engagement with thecam groove 23 in the disk 24. when then the shaft 2| is turnedclockwise, Fig. 1, by means of the handle 49 the arm 43 will swing thearm 20 to the right, so that the bar II which is taken along performsits setting movement and during this movement, as described above,causes the setting of the drum l0 and appertaining type wheels 6,whereafter the pin 48 in the shaft 2| is moved into the groove 41 whichhas such a depth that the shaft 2| and consequently the pin 22 areretained in inoperative position with respect to the cam groove 23.

The shaft 4 can now be caused to rotate for effecting any number ofstampings, without any alteration taking place in the set value, becausethe setting mechanism has been released from the machine in the setposition. When the last stamping has been effected, the shaft 2| ismoved back, until the pin 48 again falls into the groove 46, and duringthis operation flrstly the arm 20 and consequently the bar I8 are movedback into the initial position, the arms l5 and the toothed drums llbeing thereby carried back into zero position as described above,whereupon the shaft 2| is moved axially by the spring 42, so that thearm 20 is moved out from the forked end of the arm 43 and the roller 22is again moved into engagement with the groove 23 in the disk 24. Allparts have'now been restored to normal position, in which ordinarystamping may take place in the manner first described.

As will be understood the detailed construction may be varied in severalmanners without departing from the scope of the invention. Thus betweenthe type wheels and the toothed drums an indirect connection may bearranged, and a regulation may be effected by acting upon thisconnection.

The setting may also take place by direct movement of the setting armsI! manually by external means for setting the drums axiallyindependently of each other, for instance as indicated in Fig. 6.According thereto each arm I! is provided with a handle I, andprojections 50, preferably spring-pressed, are arranged on the top sideof member H to arrest the arms I! in their several adjusted positions.
